C1 Inactivator overexpression 293T lysate (whole cell) (ab94134)

Overview

Product name

C1 Inactivator overexpression 293T lysate (whole cell)

Description

C1 Inactivator overexpression lysate

General notes

ab94134 is a 293T cell transfected lysate in which Human C1 Inactivator has been transiently over-expressed using a pCMV-C1 Inactivator plasmid. The lysate is provided in 1X Sample Buffer.
Note: For more details about how the transfected lysate was prepared view preparation notes

Function: Activation of the C1 complex is under control of the C1-inhibitor. It forms a proteolytically inactive stoichiometric complex with the C1r or C1s proteases. May play a potentially crucial role in regulating important physiological pathways including complement activation, blood coagulation, fibrinolysis and the generation of kinins. Very efficient inhibitor of FXIIa. Inhibits chymotrypsin and kallikrein.
Disease: Defects in SERPING1 are the cause of hereditary angioedema (HAE) [MIM:106100]; also called hereditary angioneurotic edema (HANE). HAE is an autosomal dominant disorder characterized by episodic local subcutaneous edema and submucosal edema involving the upper respiratory and gastrointestinal tracts. HAE due to C1 esterase inhibitor deficiency is comprised of two clinically indistinguishable forms. In HAE type 1, representing 85% of patients, serum levels of C1 esterase inhibitor are less than 35% of normal. In HAE type 2, the levels are normal or elevated, but the protein is non-functional.
Similarity: Belongs to the serpin family.
PTM: Highly glycosylated (49%) with N- and O-glycosylation.
Can be proteolytically cleaved by E.coli stcE.
